Using the treatment progress report, it is possible to check whether the treatment goal is consistent with the treatment goal plan and recalculate the goal and process if necessary to maintain, change, or terminate the planned treatment procedure.

The device 1 may display the difference between the treatment result and the treatment goal plan through data overlapping using the treatment progress report. For example, during treatment, the current tooth arrangement 1510 and the treatment target tooth arrangement 1530 may be displayed on one screen, and the current tooth arrangement 1510 and the treatment target tooth arrangement 1530 are overlapped and displayed together ( 1520) can be done. The user may better check the difference between the current tooth arrangement 1510 and the treatment target tooth arrangement 1530 through the overlapping screen.

So far, the present invention has been looked at mainly by its embodiments. Those skilled in the art to which the present invention pertains will be able to understand that the present invention may be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be reflected from a descriptive point of view, not a limiting point of view. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope should be construed as being included in the present invention.
